Wings of Existence
Wings carry a number of associations: they may accompany images of Christian angels, fairies, spirits, and demons. They not only represent the ability to fly, but also suggest the improvement of the subject. But there is also a different side to wings. Bird flight is one of the most complex forms of locomotion in the animal kingdom. The shape of the wing is important in determining the flight capabilities of a bird. Humans have for a long time envied the birds’ ability to fly. Since ancient times scientists have studied and built prototypes of wings and flying implements. Leonardo da Vinci was not only an artist but also a scientist studying bird’s flight and building flying machines.
